非饱和黄土抗拉强度的研究

分析了非饱和黄土抗拉强度的来源，研究了非饱和黄土抗拉强度的特性，结果表明：密度和含水量是非饱和黄土抗拉强度的主要影响因素；百饱和黄土在拉应力下的破坏一般为脆性破坏；抗拉强度与初始含水量呈幂函数关系；试样破坏时的极限拉应变随初始含水量的增大而变大。

Study on Tensile Strength of Unsaturated Loess

The tensile strength of unsaturated loess (TSUL) is analyzed, and the properties of the TSUL are studied. The results show that: the density and water content of loess are the major factors affecting the TSUL; the destruction of unsaturated loess by tensile stress is generally brittle failure; the relationship between the tensile strength and the initial water content is an exponential function; and the limit tensile strain increases with the initial water content.
